Title: Method for determining condensed phosphoric acid
Inventor: FUKUSHIMA RYOSUKE
IPC: G01N31/00
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To enable the concentration of condensed phosphoric acid to be measured efficiently by measuring an orthophosphoric acid value during total-phosphor measuring time, and subtracting the orthophosphoric acid value from a total phosphor value. SOLUTION: A measuring system 1 is in a line of a mixing vessel 6 - an ultraviolet oxidation decomposer 7 - a measuring tube - a measuring cell 9, and an orthophosphoric acid measuring system 2 is in a line of a mixing vessel 6 - a measuring tube - a cell 9. The measuring system 1, after measuring the sample water sampled, injects a reagent and causes oxidation decomposition of the sample water with ultraviolet radiation using the decomposer 7. From the start to end of the decomposition, the measuring system 2 injects a reducing agent and a coloring agent into separately measured sample water, measures its orthophosphoric acid value, and temporarily stores the measurement. The measuring system 1 injects the same reducing and coloring agents into the sample water that has been oxidation decomposed, and measures its total phosphor value.  By subtracting the orthophosphoric acid value from the total phosphor value during the measurement of the total phosphor value, a condensed phosphoric acid value can be obtained, so that efficient measurements are made possible.

The bore diameter and the bore density of the numerous bores on the base material are in the range sufficient to give cuttability by hand to the base material. The bore diameter is 2 μm-4 mm. The bore density is 4-400 bores/cm<2> . A highly viscous adhesive having a viscosity of 8,000-70,000 cps is used to prevent the adhesive from going through the film. The thickness of the adhesive layer is 10-50 μm. Needles 4 of the needle roll 1 penetrate through a thin film of the resin film 3 into a soft material of the flat roll 2 to form fine bores 5. Burrs around the bores 5 are flattened by a heat treatment.
